How do I drop a MongoDB database, from the command line?Pro Tip: after dropping a database, you might want to exit the mongo shell and delete your ~/.dbshell file to clear your command history. (There may be a better way of doing that - I'm not sure.)
I do this because, unlike with SQL, the mongo command to drop a database does not actually reference the name of the database to drop - it just drops the database to which the client is currently connected. Clearing your command history will prevent your from accidentally replaying the dropDatabase command and unintentionally dropping a second database.
